Chapter 11, Problem 11B.11AE

Interpretation Introduction

Interpretation:

The molecules that show pure rotational microwave spectrum have to be identified.

Concept introduction:

Raman scattering is a result of rotational transitions.  The selection rule for rotational Raman spectrum is that it should be polarizable.  The molecules must acquire an induced dipole moment even if it has a permanent dipole moment.  Usually, all linear diatomic molecules irrespective of whether they are homonuclear or heteronuclear molecules, they are Raman active as they can be polarized.
